You should have a strong -understanding of tutorials #1-3 before working through these timesaving -techniques. Lines which begin with >>> mark exercises you should -try. When you want to exit this tutorial type 'Z''Z' . - - -CASE CONVERSION ---------------- -When you want to change an upper-case character to a lower-case -character (or lower-case to upper-case) there is a single command which -does both: - - '~' (tilde) Convert case of current character - ->>> Move the cursor to be OVER the first character in the example ->>> line below. Press '~' until you have changed the case of the ->>> entire line. ( '~' will advance to the right automatically). - - bOB WENT TO pARIS, fRANCE, TO SEE THE #1 CYCLING EVENT. end. - -Note that '~' only affects alphabetic characters. - - -UNDOING -------- -* EMACS-NOTICE: Uppercase U does the same thing as lowercase u in - Viper so this part of the tutorial which was about U has been - removed. - - -REPEAT LAST COMMAND -------------------- -Often you want to make the same change at multiple locations in the -file. To help accomplish this, vi remembers your previous action. - - '.' (dot) repeat last change - ->>> Go through the example below changing "FISH" to "TOAD": ->>> Go to the "F" in the first instance of "FISH" ->>> To change the word: type 'c''w' then type TOAD then press ESC ->>> Move the cursor to "F" in the second occurence of "FISH" ->>> Type '.' (dot) ->>> Move the cursor to "F" in the final occurence of "FISH" ->>> Type '.' (dot) ->>> Now move the cursor to each occurence of "CROW"; Type '.' (dot) - - EXAMPLE: The FISH fed the cat. The CROW fed the cat. Example - text is FISH to make interesting. The man fed the CROW. The - worm fed the FISH. Example text is hard to make CROW. END. - ->>> Go through the example above deleting all occurences of "TOAD": ->>> Move to the beginning of the EXAMPLE paragraph above. ->>> Type '/''T''O''A''D' and press RETURN (recall tutorial #2) ->>> Delete the word by typing 'd''w' ->>> Type 'n' to move to the next occurence of "TOAD" ->>> Type '.' (dot) to repeat the dw command ->>> Use 'n''.' to delete the remaining "TOAD"s - -Note that '.' only repeats changes, not cursor movements. - -* EMACS-NOTICE: In Emacs '.' also repeat undo and redo. - -* EMACS-NOTICE: Emacs KEYBOARD-MACROS are very powerful for repeating - whole sequences of keyboard commands. - - -WINDOW ACTIONS --------------- -You are already familiar with the C-u (depress the control key and -type u) and C-d commands from tutorial #1. - - C-d Move DOWN one half-screen - C-u Move UP one half-screen - -There are several related commands: - - C-f Move FORWARD one full-screen - C-b Move BACKWARD one full-screen - - C-e Move the window down one line without moving cursor - C-y Move the window up one line without moving cursor - -The C-e and C-y commands may seem obscure; however, notice that on -the keyboard, e and y are close to d and u respectively. This -should help you remember that C-e moves DOWN, and C-y moves UP. - -Recall the 'H' 'M' 'L' (HIGH MIDDLE LOW) window commands from Tutorial 2. -Consider a scenario where you want to yank from the current line to a -line near the top of the window. You could use C-e and C-y to -position the text in the window before you use the yH command. - -The 'z' command also moves the window without moving your cursor: - - 'z' Position the current line to top of window - 'z''.' Position the current line to middle of window - 'z''-' Position the current line to bottom of window - ->>> Move to this line. Type 'z' and press RETURN. Notice that ->>> this text and the cursor have moved to the top of the window. ->>> Try 'z''-' and 'z''.' also. - - -FILE AND DISPLAY CONTROL ------------------------- - -* EMACS-NOTICE: In vi C-g shows the status of the current file, but - C-g in Emacs in most situation stops what Emacs is doing. To get - information about the current file you can use C-c C-g instead when - Viper is in vi state. - -* EMACS-NOTICE: In vi C-l refreshes the screen, but C-l in Emacs calls - the command recenter. - - -SUSPENDING VI -------------- -* EMACS-NOTICE: In vi C-z suspends vi. However in Viper C-z is by - default the VIPER-TOGGLE-KEY. To suspend or iconify Emacs use C-x - C-z. - - -BANG COMMAND ------------- -* EMACS-NOTICE: Emacs has builtin commands to sort etc. - -The exclamation point, '!' (aka BANG), command allows you to feed text -to any Unix command. The output of the Unix command replaces the -original text. Here is a useful Unix command to use from within vi: - - !}fmt Format the paragraph, joining and filling lines to - produce output lines of up to 72 characters - ->>> Move to the example paragraph below. Type !}fmt and press ->>> RETURN. Notice the paragraph will be reformatted such that ->>> the lines are of approximately equal length. - - EXAMPLE: - So we grow together, - Like to a double cherry, seeming parted, - But yet an union in partition; - Two lovely berries moulded on one stem; - So, with two seeming bodies, but one heart; - END. - -Another useful command is: - - !}sort Sort lines of a paragraph alphabetically - ->>> Move to the example text below. Type !}sort and press RETURN. - - OBERON king of the fairies. - PUCK or Robin Goodfellow. - HERMIA daughter to Egeus, in love with Lysander. - HELENA in love with Demetrius. - LYSANDER in love with Hermia. - DEMETRIUS in love with Hermia. - -Remember, any Unix command may be used this way. - - -SHIFTING TEXT -------------- -It is possible to shift large blocks of text right and left with the '>' -and '<' commands. - - '>'movement Shift right to where the movement command specifies - '<'movement Shift left to where the movement command specifies - -These commands work like the 'd' command. For example: - - '>''}' Shift right to the end of the paragraph - '<''}' Shift left to the end of the paragraph - '>''>' Shift the current line right - '<''<' Shift the current line left - ->>> Move the cursor to the first line of the paragraph below. ->>> Type '>''>' and '<''<' to shift the line back and forth. Next ->>> try '>''}' to shift the paragraph to the right, then '<''}' to shift ->>> it left, then type '.' until all four lines start at the left edge. - - THIS IS THE FIRST LINE OF EXAMPLE TEXT - IS - EXAMPLE - TEXT END - - -SUMMARY -------- - - '~' (tilde) Convert case of current character - - 'U' * EMACS-NOTICE: Same as lowercase u undo in Viper. - - '.' (dot) repeat last change - - C-d Move DOWN one half-screen - (depress the control key and type d) - - C-u Move UP one half-screen - (depress the control key and type u) - - C-f Move FORWARD one full-screen - C-b Move BACKWARD one full-screen - - C-e Move the window down one line without moving cursor - C-y Move the window up one line without moving cursor - - 'z' Position the current line to top of window - 'z''.' Position the current line to middle of window - 'z''-' Position the current line to bottom of window - - C-c C-g Show status of current file - C-l Recenter - - '!'}fmt Format the paragraph, joining and filling lines to - produce output lines of up to 72 characters - - '!'}sort Sort lines of a paragraph alphabetically - - '>'movement Shift right to where the movement command specifies - '<'movement Shift left to where the movement command specifies - - -These commands should significantly speed up your editing. Have a nice -day. Tutorial 6 contains even more nifty commands. - -Copyright (c) 1992 Jill Kliger and Wesley Craig. All Rights Reserved. -- cgit v1.2.3-54-g00ecf
