Hot buttons of the web application interface

Question

User interface

What hot buttons to make for the interface of a web application, given the occupied by the browser? There are blocks on the panels and tabs at the main window. Somewhat similar to NetBeans main mode.

Buttons are needed for actions:
- switching tabs (Ctrl-PageUp and Ctrl-PageDown are occupied by the browser for a similar action)
- switching between blocks on panels (TAB and Ctrl-TAB are already occupied in the interface, you cannot touch it)
- "Save document" (Ctrl- S catches the browser. Although probably figs would be with him in this case)
- open a tree branch (probably the "Right" button?)
- close the tree branch (probably the "Left" button?)
- create a tree element
- rename the tree element
- delete the tree element
— tree element properties

A tree is just a multi-level list with elements.

Thanks for the opinions and tips!

Answer 1

It's better to let the user customize them. Because it’s not a fact that half of your “hot” keys, no matter how carefully you think through them, will not be used by a specific user for other purposes (for example, put something on super + q, and for the user this keyboard combination kills the browser ...) .

Answer 2

I agree with the previous commenter.
But I will offer my own list:
We need buttons for actions:
- switching tabs - ALT + arrows as an example, or ALT + SHIFT + arrows, it's difficult here, because Ubuntu can be configured to switch between desktops for these combinations. You can use < and > for navigation instead of arrows
- switching between blocks on the panels - as above, but through alt, for example
- "Save document" CTRL + S - no options, it saves the html page, which is essentially not needed by anyone now
- open a tree branch (probably the "Right" button?) in general yes
- close the tree branch (probably the "Left" button?) similarly
- create a tree element - N (new)
- rename tree element - E(edit) or R(rename) or M(move)
- delete tree element - D(delete)
- tree element properties - P(preferences) or S(settings)
